In this paper we investigate the class of finite soluble groups in which every subnormal subgroup has normal normalizer. In particular we prove that they are UN_2U, where U and N_2 denote finite abelian groups and finite nilpotent groups of class at most 2.

In this paper we investigate the class of finite soluble groups in which every subnormal subgroup has normal normalizer. In particular we prove that they are UN_2U, where U and N_2 denote finite abelian groups and finite nilpotent groups of class at most 2.
